executor of the estate, filed the federal estate tax return indicating that no federal estate tax was due by reason of the unlimited marital deduction. Fischer was survived by his wife, Rose Fischer. Upon audit, the Internal Revenue Service denied the unlimited marital deduction, and reduced the marital deduction to one-half of the corrected adjusted gross estate and assessed a tax of $294,956.94. Liberty, on behalf of the estate, paid that amount, together with $101,528.96 interest. Liberty initially filed a claim for a refund which was denied, then filed a suit in district court. The district court held that the transitional rule did apply to limit the marital deduction, and therefore granted the government’s summary judgment motion.
Liberty asserts on appeal that the district court erred in holding that the marital bequest in the will of decedent is subject to the ERTA transitional rule, which limits the estate tax marital deduction to fifty percent instead of an unlimited amount. The decedent’s marital bequest states:
(b) If she survive me, I give to my wife, Rose Fischer, the fractional share of my residuary estate which shall be equal to the maximum marital deduction allowable in determining the Federal Estate Tax payable by reason of my death, diminished by the value of all other property interests included in my gross estate for Federal Estate Tax purposes, and which pass or have passed from me to my wife in such manner as to qualify for the sáid marital deduction. In making .the computations necessary to determine such fractional share, the final determi- : nation in the Federal Estate Tax proceeding shall control.
Whenever used in this ITEM, the Words “marital deduction”, “gross estate” and “pass” shall have the same meaning as said words have under the provisions of the Federal Internal Revenue Code applicable to my estate.
Prior to 1976, marital deductions were limited to fifty percent of the decedent’s adjusted gross estate. In 1976, the tax code was amended to limit marital deductions to fifty percent of the adjusted gross estate, or $250,000, whichever was greater. 26 U.S.C. § 2056(c)(1) (1954) (amended 1981). Then in 1981, Congress provided for an unlimited marital deduction for estates of decedents dying after December 31, 1981. 26 U.S.C. § 2056(a) (1954). However, ERTA § 403(e)(3), the transitional rule, provides that § 2056(c)(1) applies as it existed prior to the amendment, that is, calling for the limited deduction, if:
(A) the decedent dies after December 31, 1981,
(B) by reason of the death of the decedent property passes from the decedent or is acquired from the decedent under a will executed before the date which is 30 days after the date of the enactment of this Act, or a trust created before such date, which contains a formula expressly providing that the spouse is to receive the maximum amount of property qualifying for the marital deduction allowable by Federal law,
(C) the formula referred to in subpara-graph (B) was not amended to refer specifically to an unlimited marital deduction at any time after the date which is 30 days after the date of enactment of this Act, and before the death of the decedent, and
(D) the State does not enact a statute applicable to such estate which construes this type of formula as referring to the marital deduction allowable by Federal law as amended by subsection (a), then the amendment made by subsection (a) shall not apply to the estate of such decedent.

The purpose of this transitional rule is to prevent an unintended testamentary disposition in wills executed before September 12, 1981, that contain a maximum marital deduction “formula clause.” Congress was concerned that formula clauses in wills drafted prior to 1981 could operate to make the marital deduction applicable to the entire adjusted gross estate rather than fifty percent of the estate.
